I am wondering, anybody can help me how can I find an implemented version of Leech-Lattice quantizer/decoder, i.e., "Matlab", "C++" or "Python" code, using the approach proposed by Ofer Amrani and Yair Be'ery in "The Leech Lattice and the Golay code: Bounded-Distance decoding and multilevel construction" or "Efficient bounded-distance decoding of the Hexacode and associated decoders for the leech lattice and the Golay code" papers.

Have they found something better for the Golay code than the tailbiting trellis of Forney et al? Have you asked them directly? I'm sad to say I didn't know about this paper (even though I refereed Amrani & Be'ery paper on multilevel construction of RM-codes). Probably need to start working seriously again :-)
